Matthew 6:30

If then God so clothe the grass, which is to day in the field, and to morrow is cast into the oven; how much more will he clothe you, O ye of little faith?

And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?

For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away:

Which when Jesus perceived, he said unto them, O ye of little faith, why reason ye among yourselves, because ye have brought no bread?

And he saith unto them, Why are ye fearful, O ye of little faith? Then he arose, and rebuked the winds and the sea; and there was a great calm.

Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.

And he said unto them, Why are ye so fearful? how is it that ye have no faith?

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither.

When the wicked spring as the grass, and when all the workers of iniquity do flourish; it is that they shall be destroyed for ever:

He answereth him, and saith, O faithless generation, how long shall I be with you? how long shall I suffer you? bring him unto me.

Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.
